Dave and Katie walked down the remote Costa Rican beach, holding hands. The weather was perfect, in the mid-80s, with a soft breeze that made the coconut palms sway gently. The warm turquoise water was crystal clear. The offshore reef kept the water calm and flat, as frigate birds circled slowly in the sky, far above. A few people lounged in a sandy area near the small parking lot. Then the beach got rocky and empty.
"If we keep heading down the beach, maybe we'll find an empty spot and have the whole place to ourselves, babe." Dave was feeling exuberant.
"Let's go!" Katie exclaimed, smiling, and holding his hand tighter. He smiled big and squeezed her hand.
They walked for half a mile, then came to a deserted cove where a rocky point curled around at the end of the beach. Happily, they set down their packs and spread their big towel on the one patch of soft, white sand amongst the small rocks.
Giving him a flirtatious glance, Katie pulled off her top, exposing her beautiful, full breasts and pale nipples to the warm sun, which felt so sensual on her skin.
Dave thought his smile might break his face. "Let's get in the water!"
"Yep!" She smiled radiantly.
For an hour they swam and explored the soothing, warm water, taking turns with the mask and snorkel. With each exchange of the mask, they held each other and kissed deeply. Back on the beach, they dozed contentedly in the sunlight, holding each other close.
Dave woke first at the sound of voices. Another couple was walking down the beach toward the cove. As they approached, they waved and gave friendly smiles. Younger than Katie and Dave, they were in their 30s. Both were blond. He was tall with strong arms and legs. She was slender and well-toned, and, like Katie, had shed her top. They could be yoga instructors, Dave thought.
Katie stirred from her nap as Dave told her, "We have company." When she looked concerned, he reassured her. "They seem perfectly friendly." Katie relaxed and smiled. "They're a good-looking couple."
"What are the odds? Two good-looking couples on the same beach," he smiled.
Approaching their spot, the young man asked, "Would you mind if we shared this bit of sand with you? Looks like the only place without rocks."
Dave and Katie exchanged a glance, then said "sure" in unison. Katie had covered her breasts as the couple walked up, but she dropped her arms as they got close. Blushing, she looked the handsome young man in the eye as he thanked them. The woman smiled warmly and made no effort to cover her perfect small breasts. The sandy area was not large, so they laid out their towels just a few feet away.
"I'm Jack and this is my wife, Marie. We're from New Mexico, here to celebrate our anniversary. How about you two?"
Dave explained they were celebrating Katie's birthday, and recently had their first anniversary. Marie asked how they had met. Marie and Jack sat close to each other as Katie and Dave told them the story.
After a few minutes Jack and Marie ran out into the water. As their new, young friends splashed about like otters, Katie and Dave stretched out again, marveling at the idyllic place they had found. They kissed passionately.
Watching them emerge from the water, Katie was struck again by how attractive Marie and Jack were. She noticed the beads of water running down their toned bodies in the bright clear light. Marie's small nipples were erect.
So were Katie's.
Returning to their blanket, Marie asked if Dave and Katie minded if they took off their wet things. "Not at all," Katie quickly responded. Dave did not object.
Marie slid off her bikini bottoms and Jack peeled off his swimsuit. Not surprisingly for their age, neither had a trace of body hair. They looked incredibly good naked. Dave and Katie did their best to seem nonchalant, while stealing glances: at Jacks long, thick cock between his powerful legs and Marie's lovely body and glistening, shaved pussy. Getting completely naked just feet away, Marie and Jack seemed entirely comfortable and unselfconscious.
After drying off, Marie stretched out on the towel, lying on her stomach. Sitting next to her, Jack lovingly applied lotion, starting at her long neck, then moving down her back. As he reached her bottom, he straddled her, facing her feet. Out of the corner of his eye, Dave watched as Jack worked the lotion into her skin, kneading Marie's ass so her cheeks spread open, then closed. Dave caught Katie looking too; Jack's cock was swelling as he massaged his sexy wife.
Jack whispered in her ear and Marie turned over. Straddling her hips, he carefully applied lotion to her face and ears and neck, then moved down to her chest and breasts, where he lingered, softly pinching her erect nipples. Dave felt his own cock twitch when Jack rubbed lotion onto Marie's belly, then down to her pussy, pulling her lips open and closed. Dave saw Marie was wet. Marie met his gaze with a smile, her eyes half closed.
Then it was Jack's turn to lie down. Marie straddled his back and massaged lotion into his back. When Marie squeezed his muscular ass, Katie quivered. When Jack turned over, Marie moved down from his chest and rubbed lotion on his hardening cock, giving it long, slow pulls. She gave Katie a mischievous look; Katie tried to avert her eyes but could not help but smile and watch intently.
"We could use some lotion ourselves, baby," Dave said with a sly smile. "And when in Rome..." He pulled off his bathing suit, then slid her bottoms off as, without hesitation, she lifted her hips to help. While older than their new companions, Katie and Dave were still fit and attractive. Jack and Marie watched intently from just feet away.
